Table 2-4, Performance Test Record for the Agilent E1446A Amplifier, is a
form you can copy and use to record performance verification test
results for the amplifier. Table 2-4 shows amplifier accuracy,
measurement uncertainty, and test accuracy ratio (TAR) values.
Test limits are defined using the specifications in Appendix A of the
Agilent E1446A User's Manual. The specifications for Bandwidth are
single-sided (i.e., there is a lower limit but no upper limit). In the
Performance Test Record, the Maximum column will be blank for the
Bandwidth Test.
For the performance verification tests in this manual, the measurement
uncertainties are based on the accuracy specifications for the following
test equipment:
Performance Test
1. Input Attenuation
2. Output Attenuation
3. Low-Level Outputs
4. Main Output
5. Offset DAC
6. Bandwidth
Test Accuracy Ratio (TAR) for the Agilent E1446A is defined as:
Amplifier Accuracy divided by Measurement Uncertainty, i.e.,
Maximum − Expected Reading
TAR =

Measurement Uncertainty

For single-sided measurements, Test Accuracy Ratio is not defined, so
'NA' (Not Applicable) will appear in the TAR column. For TARs that
exceed 10:1, the entry is '> 10:1'.
